Via Curbed LA: Architect Alfred Rosenheim, known for designing Los Angeles monuments such as downtown's Hellman Building, the Hamburger Department Store, and the Eugene W. Britt House, designed this as a home for himself in the early 1900s. Now a registered Los Angeles Cultural Monument, this Country Club Park mansion is on the market for $4.5 million. The three-story, 10,440 square foot house has six bedrooms, five bathrooms and sits on almost an acre of land alongside a former chapel that is now used as a recording studio. Details like stained-glass windows and silver and gold leaf painted ceilings complete the estate's classic, elegant look and, according to the official listing, evoke "the quality and grandeur of a bygone era."
